Stargate Command (abbreviated to SGC) is a top-secret Federation organization founded and led by the United Federation of Planets in conjunction with the International Oversight Advisory, tasked with operating the Stargate device and all matters pertaining to things offworld, such as threats to Earth or missions to procure new technology from extraterrestrial civilizations. It is based inside the Cheyenne Mountain Complex in Colorado, codenamed "Area 52". It is typically commanded by a General and is staffed by subject matter experts and Starfleet, Starfleet Marine and MACO support personnel, several elite special operations teams, and several SG teams, including SG-1, the SGC's main flagship team.


Unbeknownst to the public, however, Cheyenne Mountain has for the past few years also been home to Stargate Command. Cheyenne Mountain contains nearly a skyscraper's worth of floors, but with one significant difference to a skyscraper; instead of going 20 or more floors up, it instead descends an unknown number of levels under the mountain. While the full extent of the facilities available to personnel within Cheyenne Mountain is unknown, it is at least certain that the complex sports several cafeterias and troop's barracks, at least one gym, a fully equiped infirmary, and several multi-purpose observation rooms, which are used for such things as complex surgery, interrogation, imprisonment, and volatile scientific experiments. By 2404, Vice Admiral Typhuss James Kira was in command of Stargate Command at the Cheyenne Mountain Complex in Colorado Springs, Colorado on Earth. Typhuss's heroism during his long Starfleet career earned him a promotion to the rank of Admiral in 2409.


The SGC is located one thousand meters beneath Cheyenne Mountain. This protects it from most forms of attack, including indirect nuclear detonations, and allows containment of biological or chemical hazards (the base may be 'locked down'). However, it was shown in an alternate reality to be unable to withstand a direct Goa'uld attack. The primary function of the base is to protect Earth. Simultaneously, it exists to coordinate exploration and diplomatic relationships. It is the core of the Stargate program, the mission of which is to procure technology that can defend Earth, and make offworld allies. The SGC serves as one location for researching alien technology with larger or longer term research projects being conducted at Area 51 off-site in Nevada. On more than one occasion, SGC personnel have had to recapture alien technology that has escaped into the outside world. Many cover stories have been generated to keep the general populace, even high-ranking government officials, unaware of the goings-on within the SGC.

SGC facilities and technology[]


The SGC's dialing computer

The SGC extends many levels beneath the ground, officially called sub-levels. At level 27 is the briefing room and the Commander's office. The Embarkation room with the Stargate is at level 28. The Gate is dialed from the Stargate Operations room above using the dialing computer, from where Commanders are also able to use a microphone to give orders. There is a long ramp in the middle of the Gateroom leading up to the Stargate, allowing vehicles (such as the MALP robot probe) to enter the Stargate, as well as easier access by persons. (Most other Stargates are partially in the ground, waiving their need for a ramp) As a relic of the days when the complex was a missile silo, the ceiling opens and the Stargate may be lifted in and out of the Embarkation room; this also allows Puddle Jumpers to access the room.

The Stargate with a closed iris

Hostile aliens such as the Goa'uld are usually prevented from entering the SGC through the Stargate by use of 'the iris'. This is a device that creates a barrier a few micrometers in front of the event horizon of the Stargate, keeping any matter from fully rematerializing, thus preventing the passage of dangerous objects and/or entities. The iris also prevents the formation of the unstable vortex usually seen when the wormhole is first established. It can be opened for the return of an SG team, but is closed if there is an alien attack. The Iris is made up of a Trinium-Titanium alloy, having replaced the original Titanium iris. 

The iris red hot

In the event that either the iris is penetrated or must be kept open because an SG team is returning under enemy fire, standard procedure dictates that a heavily armed defense team must be present, with their weapons ready, in order to provide defense in case of hostiles coming through the Stargate.


The SGC self-destruct device

If the SGC is threatened with invasion, the facility has a self-destruct mechanism, which has been activated more than once. It requires at least two high-ranking officers to initiate or deactivate (although the computer system may be manipulated so as to avoid this requirement). Alien takeover of the SGC is referred to as a "Foothold situation".

However, according to Lieutenant Colonel Samantha Carter, the self-destruct is not powerful enough to destroy the Stargate, and has only a minimal chance of disconnecting an active wormhole. It would however bury the gate under 1000 meters of rock, thereby stopping any more incoming travelers. Even with these shortcomings, it remains the best backup plan available in the event of a hostile alien takeover of the SGC.

Alternative sites[]

  • Alpha Site - The last line of defense for the SGC is an off-world base, called the "Alpha Site", which was initially set up as a settlement to evacuate a select number of the academic elite of the Federation to in case of Goa'uld invasion. It was later established as a back-up in case anything were to happen to the SGC. The Alpha Site was also known as the "Beta Site" in an alternate reality. After the first and second Alpha Sites were destroyed, the replacement was built into a mountain much like the SGC.
  • Beta Site - The second base set up by the SGC was called the Beta Site.
  • Gamma Site - The Gamma Site was an off-world research base equipped with F-302 fighters but was destroyed via self-destruct.

Alien technology[]

The SGC has been shown to possess various different technologies acquired from offworld. The presence of Naquadah generators, supplementing the base's power supply, was confirmed in 2379. The base is shown to have Tok'ra force fields protecting the isolation rooms, Carter also states that 'the emergency force fields are in effect', suggesting that the force field technology is not limited to one specific section of the base.


Attempted shutdowns and takeovers of the SGC[]

Robert Kinsey

On many occasions the very existence or control of the SGC has been in threat. Senator Robert Kinsey has often made strong efforts to close down the entire Stargate Program, arguing that the existence of the program is far too great a threat to Earth. Richard Woolsey, an inspector, recommended the closure of the SGC to the President, arguing that SG-1 were a reckless team that more than once had caused the Earth great threat. Kinsey later on tried various methods of putting himself in power over the SGC, mainly through links with rogue NID leaders, who have tried to sabotage the base on many occasions, once even succeeding in stealing the Stargate itself.

On a few occasions, aliens have managed to permeate the iris. The Tollan possess technology capable of allowing people to pass through matter, but were never considered a threat owing to their friendship with Earth. At least once, the base was compromised by aliens with unforeseen abilities. Anubis, a powerful System Lord with access to Ancient technology, has tried to destroy the SGC via various methods, including the detonation of the Stargate itself with the Stargate destroyer. All attempts to subsume or destroy the SGC to date have failed.
